Half-Inch One Deck Rotary Switch Spring Return Action/Momentary Positions

A 1800 Spring Return Rotary Switch has a spring return mechanism which allows for momentary positions. A momentary position is active only as long as the operator holds the knob in that position; when the operator releases the knob, a spring returns the switch back to an adjacent position. This prevents the switch from remaining in a certain position when the operator lets go of the knob. This feature is available throughout COLE's rotary switch product lines.

The SERIES 1800 spring return mechanism adds 0.160 inches to the behind panel length of the switch; all other dimensions remain unchanged.

The SERIES 1800 spring return mechanism is available in switches with 36 indexing (10 positions max) and 45 indexing (8 positions max). Cole Instrument Engineering and Design capabilities are available to customer with Special Application requirements.
