Spade type terminals are crimped on to the ends of lead wires. After such crimping the terminals are inserted into the housing of a switch and lock in place. The switch is provided with a toggle actuator to effect movement of a movable switch contact with a snap action between the inserted terminals serving as fixed contacts.

A snap action slide switch is provided having a contactor assembly engaging a common contact and selectively engaging one of a plurality of discrete contacts. A slider extends outwardly through a slot in a housing containing the contacts and has legs extending over the ends of a spring seated in the contactor assembly thereby biasing the contactor assembly to move with the slider. Projections on the contactor assembly engage notches on the housing to position the contactor assembly in engagement with a selected discrete contact and the common contact and to restrain the contactor assembly from movement with the slider. Movement of the slider relative to the contactor assembly compresses the spring and moves a cam depending from the slider into engagement with a cam surface on the contactor assembly. Relative movement between the cam and cam surface produces pivoting of the contactor assembly and removal of the projections from the notches permitting the force of the compressed spring to snap the contactor assembly into engagement with another of the discrete contacts.

A snap blade construction comprising a generally rectangular flat blade having side strips interconnected at each end. Extending inwardly from the side strips are projections or fulcrums. A self-retaining post member is inserted between the projections to stress the blade so that it will assume either one of two stable states and will move with a snap action between the two states.

The invention concerns dictating and transcribing apparatus using a magnetic belt record media and having a variety of automatic and semiautomatic features. The dictating and transcribing units are arranged for loading and unloading of a magnetic belt and have an automatic phasing feature for establishing initial synchronism of the driving lead screw and the belt for accurate tracking of a signal transducer in relation to the belt during recording and transcribing operations Certain procedures are provided to insure compatibility of the units with different kinds of record media.

There is disclosed an electrical switch including a plastic housing having a fixed electrical contact mounted therein, an integral plastic actuator including a pair of arms hingedly joined together and a handle for controlling the position of the arms, the outer ends of the arms being respectively swingably connected to the housing at spaced-apart mounting points thereon for snap movement between first and second stable conditions, and a movable electrical contact held against the fixed electrical contact when the arms are in the first stable condition and being held away from the first electrical contact when the arms are in the second stable condition.
