Product Data

Model 625 Slide Switch

 

Special Features

  • Simultaneous activation of pushbutton function without disturbing previously selected circuit.
  • Sub-miniature size, but with detent action and “feel” of a much larger switch.
  • Long life construction — typically in excess of 150,000 cycles.
  • Precious metal contacts with resistance typically less than 30 milliohms.
  • Available with terminals either vertical or horizontal to switch.

Model 625 Switch is a three position miniature slide switch with an OFF (open) position and two ON (closed) positions, plus an integral push button function.

  Operation

The switch is designed so that Terminals No. 1 and No. 6 comprise one circuit; Terminals No. 2 and No. 5 another; and Terminals No. 3 and No. 4 another.

When the switch knob is in Position No. 1, all functions are OFF (open).

When the switch knob is in Position No. 2, the 1-6 and 2-5 circuits are completed.  The pushbutton function is activated by depressing the switch knob.  This completes the 3-4 circuit without disturbing the other two.  The 3-4 circuit remains completed as long as the knob is depressed; when the knob is released, the 3-4 circuit is broken.

When the switch is in Position No. 3, only the 1-6 circuit is completed; and again, depressing the knob completes the 3-4 circuit without disturbing the other circuits.

Electrical continuity is maintained between Terminals No. 1 and No. 6 when the switch is moved in either direction between Positions No. 2 and No. 3.

The quality program in our Huron, South Dakota factory, where these parts are manufactured, meets or exceeds MIL-Q-9858A.
