A small switch comprising a plurality of switching elements with a hole which are oscillatably disposed one in each switch body and a single switching rod inserted through the holes of the switching elements whereby the contacts in a plurality of small switches can be made or broken simultaneously by operating the switching rod from the outside of the electronic device containing the switches. This small switch has projections and recesses on both sides of the switch body where the holes are formed so that a plurality of switches can be connected in series by fitting the projections of one switch into the recesses of other switch.
An electric switch for toys comprises a stationary member and a member rotatable with respect to the stationary member. The stationary member includes a plurality of electrical connections in the physical form of fixed, variable configured contacts with integral terminals. The contacts are bridged by conductive pattern(s) forming part of the rotatable member. Circuits are broken or made which are dependent upon the position of the rotatable member. The rotatable member includes a coupling, preferably a cruciform hole for detachably mounting a protruding lever or protruding shaft. The rotatable member can be rotated between a plurality of premarked positions when the lever or shaft is mounted within the coupling hole. The switch may be used as a building block component.
A modular electrical switch provides a wiping or shearing action upon closing and opening thereof. A contact carrier disposed within a housing linearly carries a movable contact into engagement with a stationary contact. The contact carrier is guided by movable slide plates disposed on either side thereof and movable along with the contact carrier as a contact assembly. The guide plates also provide pivot recesses for pivot bosses of the contact carrier. The contact carrier is constrained to linear motion up to the point of contact between the movable contact and the stationary contact by a cam trace in the housing. After contact between the movable contact and the stationary contact, the contact carrier reaches a pocket defined by the cam trace, ceases linear movement and upwardly pivots to provide a wiping action between the movable contact and the stationary contact. Immediately upon reversed, pivoting and linear motion of the contact carrier a shearing action is provided between the movable contact and the stationary contact. A plurality of such modular switches are utilized in a freight elevator interlock system for regulating the opening and closing of the various doors and carriage of the freight elevator. A common sliding actuator controls the modular switches regardless of the orientation of the respective switches within the housing.
