Make-before-break selector switch |
摘要 |
A make-before-break selector switch for use in high-voltage applications allows power to a load to be switched from a first power source to a second power source such that the second connection is made before the first is broken. The selector switch includes a blade coupled to a selector switch control such that the blade may be placed in a first position to electrically couple a first power source electrical contact to a load electrical contact and in a second position to electrically couple a second power source electrical contact to the load electrical contact. T-shaped and v-shaped blade implementations are examples of configurations that may be used.
