Paiste incandescent switch

Paiste Incandescent Switch.

A switch for incandescent work, designed by H. T. Paiste of Philadelphia, Pa., is illustrated in the accompanying cuts. The entire switch is stamped from sheet brass by standard dies, and all parts are interchangeable. The switch consists of seven pieces — the U-shaped main shell, side plate, two arms, spindle, spring, and hard rubber handle. The spring is attached to the ends of two arms, and is extended when the switch is operated to make or break circuit. When this is effected the spring is no longer under tension. The circuit wires are attached to the bending screws on the main shell and side plate. The arm shown in Fig. 2. completes the circuit between the side plate and main shell and through the spindle upon which it is centered, making ample electrical contact. The arrangement is such that whatever arcing might result on breaking the circuit would be on the back of the arm and not on the face where electrical contact is made. An improvement has been made in the handle. If turned backward it will simply unscrew, and straining of the working parts is avoided.
