ABSTRACT:
Single pole, triple throw battery selector switches are provided with locks to prevent unauthorized use. Rotation is prevented between the selector knob and housing by having a semicircular groove with a locking position at the end thereof in the top cover of the battery selector switch and a locking pin projecting from the underside of the selector knob into engagement with the grooves. The selector knob is locked with the batteries disengaged when the locking pin engages the locking position groove by turning a locking cylinder with a key.
