摘要： PURPOSE:To eliminate need of an auxiliary switch, and improve compactness of a key switch, reduction of cost, workability, productivity, etc., by composing the key switch to perform operation of a switch element by means of a second operation body interlocked with an electromagnetic solenoid. CONSTITUTION:Inside a case 5 provided with a key inserting hole 11, a first operation body 14 interlocked with a key inserted through the key inserting hole 11 to perform operation of a switch element 6, and a key removal prohibiting mechanism 17 interlocked with the electromagnetic solenoid 7 to prohibit removal of the key. A second operation body 8 is also provided to be interlocked with the key to operate the switch element 6. Operation of the switch element 6 is thus performed by the first operation body 14 interlocked with the key, and the second operation body 8 interlocked with the electromagnetic solenoid 7. Removal of the key is prohibited by action of the key removal prohibiting mechanism 17 interlocked with the electromagnetic solenoid 7, thereby safety in work can be secured.

摘要： PURPOSE:To output an alarm signal only in the case of a consecutive closing defect exists due to a trouble by providing a contact state storage circuit receiving a state signal of a contact part over the plural number of times within a prescribed time, and storing the state of the contact part for each time. CONSTITUTION:An origin return detection switch 4 is forcibly turned on in interlocking with the origin recovery of a switch operating body 1, an origin recovery detection circuit 5 outputs a discrimination start signal SST, a contact state storage circuit 6 fetches a state data D1 of a contact part 2 for each prescribed time from the point of time and stores it. A closing defect deciding circuit 7 fetches the contact part state data D1 for each time from the storage circuit 6, and outputs an alarm signal SAL so long as it is decided that all the contact part state data D1 show opening state for the plural number of times. Thus, a consecutive closing defect due to a trouble is distinguished clearly from a tentative closing defect due to bounce or chattering and an alarm signal is outputted only at the consecutive closing defect exists due to a trouble, then misdecision as to closing defect is evaded.

摘要： PURPOSE:To neglect a telegraphing phenomenon and output a right signal, even if this phenomenon occurs, by connecting an OFF delay circuit to the next step of a contact part. CONSTITUTION:A switch operator 2 as an actuator displaced by the contact with a moving object, a contact part 3 turned ON interlockingly with the sliding of the switch operator 2, and an OFF delay circuit 4 connected to the both terminals of the contact part 3 are provided. Even if a telegraphing phenomenon resulting from the self-resettability in which the contact part transmits repeated signals of ON/OFF occurs, the repeated signals of ON/OFF can be neglected by the OFF delay circuit 4. The switch operator 2 is nearly stabilized near the origin, and the re-inversion to ON of the contact part is never caused after the contact part is turned OFF.

摘要： PURPOSE:To enable enlarging the compressing stroke of a switch part by providing one stroke-enlarging lever. CONSTITUTION:A switch is composed of a casing 1, an operation body 4 positioned to protrude outside from the casing 1 at one end and displace- operated when it is brought into contact with, a switch part arranged in the casing 1, a stroke enlarging lever 50 rotatably supported on the inner face of the casing 1 at one side, rotated when compressed by the other side of the operation body at the intermediate position at the time of operation of the operation body and compressing a compressed part 22 of switch part in the other side. Consequently, the other end of the operation body 4 compresses the intermediate position of the lever 50 when the operation body 4 works. It is, therefore, possible for the lever 50 to push down the compressed part of switch part by the other side with the displacement amount larger than that of the operation body 4.

摘要： PURPOSE:To mount an indicator lamp to indicate actuation of a switch simply and without trouble by installing the indicator lamp in such a way as to be integrated with a circuit unit and positioned facing the indicator part of a casing cover. CONSTITUTION:A circuit unit 37 consists of a printed circuit board 38 and a mounting block 39 therefore. Various circuit elements are mounted on this circuit board 38, and an indicator lamp 40 as one of them is installed in the condition protruding long on the circuit board 38. A circuit unit 37 is mounted in a casing 1, and a lid 45 is fixed to the opening 3 of the casing. This lid 45 is equipped with a checking window 48 for the indicator lamp 40, wherein the indicator lamp 40 is located closely to the inside of the window 48 and facing thereto. Thereby no coil spring is needed when indicator lamp is to be mounted to enable simple mounting of it, and also electric shock can be prevented which is otherwise likely to occur at the time of lid removal.

摘要： PURPOSE:To prevent a switch from malfunctioning due to infiltration of liquid by issuing a warning based on a liquid detection signal of a conductive condition caused by the liquid infiltrated into a lower position below a contact point of a switching part. CONSTITUTION:When water infiltrates into a casing 1, the level of an output of a 2nd input circuit 104 becomes continuously low (liquid detection signal), a high level of input is given from an inverter 106g to an input section of a 4th D flip-flop 106d, and a high level output is issued (a failure prediction signal S11) from the 4th D flip-flop. This high level output is outputted as a failure prediction signal S13 from a failure prediction circuit 106 to light an LED (warning mechanism) 40. Even in a condition of a short circuit of a 2nd switch section 102 due to water infiltration, a 1st switch section 101 works normally and, based on the function, a device to be controlled is operated normally by means of a switch signal S12 issued from an output circuit 107. Confirming the lighting of the LED40, a correction is performed at the time a production is stopped.

摘要： PURPOSE:To provide high detection precision constantly even in the case ambient temperature alters by supporting a coil body of a differential transformer by a supporting spring, regarding a pressure sensor provided with a pressure sensitive deformable body and the differential transformer. CONSTITUTION:A pressure sensor is composed in which a pressure-sensitive deformable body 12 is deformed by pressure of a fluid introduced from a pressure introducing hole 17, a core 15c of a differential transformer 15 which works following the pressure-sensitive deformable body 12 is displaced against a returning spring 15, the mobility degree of the core 15c is detected by coil bodies 15a, 15b of the differential transformer 15, and the output reflecting the mobility degree is sent out of the differential transformer 15. The coil bodies 15a, 15b are supported by a supporting spring 43. Consequently, even in the case the circumferential parts of the sensor are expanded or contracted due to the ambient temperature alteration, the deformation stress is absorbed by the elastic force of the supporting spring 43 and does not affect the coil bodies 15a, 15b. As a result, the coil bodies 15a, 15b are always set on the opposite to each other at regular positions in the core 15c.
