摘要： A switch of the type utilized for machine tool controls and actuated by a roller passing over a cam track has two members mounted for independent reciprocation along a plunger actuated from the cam track. One of the members carries a movable contact or contacts, while the second member is utilized to trigger the first member. Each of the members is independently activated by an associated overcenter arrangement for snap action. A compression spring is utilized to return drive the plunger from the position to which it is moved by the action of the roller on the cam track. Movement of the plunger under the driving force of either the roller and cam track or the compression spring provides for a snap action of both members in the appropriate direction upon activation by their respective overcenter arrangement. The plunger is driven by the cam track to provide a positive contact break, while the compression spring provides an additional opening force in the other direction, if the overcenter arrangements for the two members do not succeed in effecting the desired contact opening.
摘要翻译：用于机床控制并由通过凸轮轨道的辊致动的类型的开关具有安装成用于沿着从凸轮轨道致动的柱塞的独立往复运动的两个构件。其中一个构件携带可动触点或触点，而第二构件用于触发第一构件。每个构件由相关的超中心布置独立地激活以进行快动作。压缩弹簧被用于通过辊在凸轮轨道上的作用将柱塞从其移动的位置返回。柱塞在滚子和凸轮轨道或压缩弹簧的驱动力下的运动，通过它们各自的中心配置的激活，在两个构件的适当方向上进行快速动作。柱塞由凸轮轨道驱动以提供正接触断裂，而如果两个构件的过中心布置不能成功实现期望的接触开口，则压缩弹簧在另一个方向上提供另外的开启力。

摘要： A key assembly for actuating a diaphragm switch, and including a housing, a keystem movably mounted on the housing, and a switch actuator coupled to the keystem through a lost-motion connection arranged so a relatively large stroke of the keystem is required to effect a small actuator motion needed to operate the switch. A coil spring biases the keystem away from the housing to an extended position in which the switch is not actuated, and a second coil spring urges the actuator away from the keystem. The lost-motion connection between the keystem and actuator provides positive retraction of the actuator during the return stroke of the keystem. A leaf spring on the keystem rides a cam surface or ramp on the housing, and the ramp is shaped to modify the effect of the coil springs such that the keystem tends to toggle past the point of switch actuation to prevent switch jitter and to provide a tactile signal that actuation has occurred.

摘要： A movable contact structure having a movable contact member carried on a movable contact carrier by a spring biased rotatable plunger. The contact member has a channellike cross section and is formed of at least two laminated metals each having different deflection and conductive characteristics so that the weight of the contact member may be reduced and provide a maximum conductive ability commensurate with its resistance to bending. An end of the plunger extends through a notched opening in the contact member so that when the plunger is rotated to one position the contact member may be separated from the carrier and when the plunger is rotated to a second position, a pin on the end of the plunger engages the material of the contact member to maintain the contact member on the end of the plunger. The plunger also includes a portion that acts as a piston in a bore of the contact carrier to reduce the bounce which occurs when the movable contact surfaces on the contact member initially engage the stationary contacts.
