摘要： A switch case has a top provided with a central opening in which slides the stem of a plunger that has a foot inside the case and a cap on its upper end. A spring normally holds the plunger in its upper position with its foot adjacent the top of the case. The foot carries a bridging contact formed from a spring having free end portions extending away from the opposite sides of the foot to form movable contacts that engage stationary contacts in the case when the plunger is depressed.
摘要翻译：开关壳体具有设置有中心开口的顶部，在该中心开口中滑动具有在壳体内的脚的柱塞的杆和其上端上的帽。弹簧通常将柱塞保持在其上部位置，其脚靠近壳体的顶部。脚承载由弹簧形成的桥接接头，弹簧具有远离脚的相对侧延伸的自由端部，以形成可动触点，当活塞被压下时，该触点接合壳体中的固定触点。

摘要： An electric switch rigidly mounted on a support has an actuating plunger that a spring normally urges outwardly in a direction away from the support. Mounted on the support beside the switch is a bushing, in which a guide post is slidably mounted parallel to the plunger. A key cap overlies the post and plunger and is rigidly mounted on the outer end of the post so that when either end of the key cap is depressed to actuate the switch the cap will be guided by the post, and the plunger will not bind in the switch.

摘要： Two laterally spaced parallel bands of electrical resistive material are applied to a dielectric surface of a linear motion potentiometer. A slide movable lengthwise of the bands carries a pair of sliding contacts, each of which engages a different one of the bands and a separate collector strip beside it. The ends of the bands are engaged by resilient electric terminals.

摘要： A switch case has a top provided with an opening in which slides the stem of a plunger that has a foot inside the case normally held adjacent the top of the case by means of a spring. The foot carries a bridging contact member formed from a spring wire coil attached to it and having free end portions extending tangentially away from the opposite sides of the plunger foot. Electrically conductive elastic members are rigidly mounted on the ends of the coil wire to form movable contacts that engage stationary contacts in the case when the plunger is depressed.

摘要： A ROTOR IN A HOUSING IS PROVIDED WITH AN AXIAL PASSAGE, IN WHICH A CONTROL SHAFT IS ROTATABLY MOUNTED. A FIRST ELECTRIC CONTACT CARRIED BY THE ROTOR ENGAGES A RESISTANCE ELEMENT IN THE HOUSING. A SECOND ELECTRIC CONTACT CARRIED BY THE ROTOR ENGAGES AN ELECTRICAL COLLECTOR INSIDE THE HOUSING AND HAS ENDS FACING EACH OTHER AT ONE SIDE OF THE ROTOR TO FORM FIXED CONTACTS. A MOVABLE SWITCH CONTACT FASTENED TO THE SHAFT EXTENDS LATERALLY BETWEEN THE FIXED CONTACTS, WHERE IT IS NORMALLY HELD CENTERED BETWEEN THEM BY A SPRING CONNECTING THE SHAFT AND ROTOR. THE FRICTIONAL RESISTANCE OF THE ROTOR TO BEING TURNED IS GREATER THAN THE RESISTANCE THAT THE SPRING OFFERS TO TURNING OF THE SHAFT IN THE ROTOR, SO WHEN THE SHAFT IS ROTATED IT WILL SWING THE MOVABLE SWITCH CONTACT INTO ENGAGEMENT WITH ONE OF THE FIXED CONTACTS TO TURN THE ROTOR. WHEN THE SHAFT IS RELEASED, THE SPRING WILL CENTER THE MOVABLE CONTACT BETWEEN THE FIXED CONTACTS AGAIN.
