Abstract
Abstract A push-button switch-actuating mechanism is integrated with one or more switch units by adding on the switch unit or units to the actuating mechanism. Detachable connections between the actuating mechanism and the unit or units enable one or more units to be added on in tandem. Latch means in the actuating mechanism enables it to be maintained in actuated position on one operation and released by the next operation. Latching and releasing springs of hairpin type constitute a novel part of the actuating mechanism.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
265 words
Electric switching apparatus comprising insulating housing means, actuating means slidably mounted in said housing means, plunger means in one end of said housing means, push button means extending out the other end of said housing and depressible to cause axial movement of said plunger means, said push button means and said plunger means being formed separately from said actuating meAns, and said plunger means being movable independently of said actuating means, a switching unit attachable to an end of said housing means in position to be operated by said plunger means, fixed and movable contact means in said switching unit, a movable contact actuator having a projection beyond one end of said switch unit, and means on said switch unit and said housing means including spring finger means on one of said parts and shoulder means on the other of said parts engaged by said finger means interengaging to enable connection and separation of those parts by axial manual pulling and pushing respectively, without disassembly thereof, and a second switch unit like the first said switch unit operable by said movable actuator of said first unit, and detachable interengaging means connecting said first and second units together, said detachable interengaging means being like the means connecting said first switch unit and said housing means in both form and location, whereby the positions of said units are interchangeable with respect to said housing means and to each other along a stack and whereby another switch unit may be directly connected to said housing means or inserted in a stack without the interfering with previously attached units.

Claim 3
Dependent Claim
210 words
Electric switching apparatus comprising insulation housing means, actuating means slidably mounted in said housing means, plunger means in one end of said housing means, push button means extending out the other end of said housing and depressible to cause axial movement of said plunger means, a switching unit attachable to an end of said housing means in position to be operated by said plunger means, and means on said unit and said housing means interengaging to enable connection and separation without disassembly thereof, by axial manual pushing and pulling respectively, said attached switching unit having fixed and movable contact means, a movable contact actuator having a projection beyond one end of the unit, and a second unit like the first said unit operable by said movable actuator of said first unit, and detachable interengaging means connecting said first and second units together, said detachable interengaging means being like the means connecting said first switch unit and said housing means, in both form and location, whereby the positions of said units are interchangeable with respect to said housing means and to each other along a stack and whereby another switch unit may be directly connected to said housing means or inserted in a stack without the interfering with previously attached units.
