3-Position Magnetically Held Toggle Switch - Locking Lever, (ON)-OFF-(ON)

A three-position toggle switch with SPDT contacts and a locking lever, function (ON)-OFF-(ON). The centre OFF position is maintained, and both outer positions are momentary and spring-loaded, each held in place by its own dedicated holding solenoid. Both (ON) positions are locked out of the centre: the lever has to be pulled out of the lock by approximately 2mm before it can be moved either way.

This is the arrangement used for JFS start and ALT/ATT style controls in F-16 style cockpits — a guarded lever that stays where you put it only while the aircraft systems hold it there, and springs back the moment they don't.

Each solenoid is driven independently by its own low-dropout regulator with an enable/shutdown input, with a flyback diode built in to protect the circuit. A limit switch prevents a solenoid from energising unless the lever is physically in that position. Supplied with a stainless steel M12x0.75mm panel bushing, hex nut, washer, tooth-style lock washer and a wire-to-board connector lead. Currently available as a 12V unit.

Note: may not be compatible with Opencockpits IOCards, as the solenoid and switch circuits share the same ground.
