A convertible switch characterized by a dielectric housing comprising a contact compartment, a pair of stationary contacts at one end of the compartment, movable contacts movable between open and closed positions, a contact carrier slidably mounted in the housing and comprising a bridging contact member upon which the movable contacts are mounted, a coil spring at one end of the contact carrier for biasing the movable contacts in one of the open and closed position, and the assembly of the contact carrier and spring being reversible within the housing compartment for holding the movable contacts in the other of the open and closed positions.

Convertible switch

A pushbutton switch structure characterized by a pushbutton switch handle and a plurality of switch blocks mounted in tandem, each switch block having an operating plunger for simultaneous operation by said switch handle carrier means associated with the plunger for carrying movable contacts between open and closed positions of stationary contacts, the plunger and carrier means having spaced complementary surface means engageable during movement of the plunger, whereby actuation of the pushbutton handle effects simultaneous operation of all of the plungers and a delay of movement of movable contacts from the normally closed position.

Pushbutton switch assembly having floating type bridging contact and

A rotary selector switch characterized by a rotatable switch actuating unit and two switch structures, the actuating unit having a shaft with multiple sides on which a cam is detachably mounted for operation in a plurality of modes to operate the switch structures in different combinations of open and closed conditions, whereby a single cam mounted on the shaft in different positions is useful to operate the switch structures in a plurality of switch combinations.
