Abstract:
A make-before-break selector switch for use in high-voltage applications, the switch comprising:a first power source electrical contact; a second power source electrical contact; a load electrical contact; a selector switch control mechanism; and a blade coupled to the selector switch control mechanism such that the blade is moveable between a first position that electrically couples the first power source electrical contact to the load electrical contact and in second position that electrically couples the second power source electrical contact to the load electrical contact, the blade comprising: a mounting point used to couple the blade to the selector switch control; and an electrical contact sized such that, when the selector switch control mechanism causes the blade to be moved from the first position to the second position in a first direction, the coupling of the first power source electrical contact to the load electrical contact is not broken until the coupling of the second power source electrical contact to the load electrical contact is made.
