Test & Control Switches
SB-1 Control & Transfer Switch
Type SB-1 Switches are rotary, cam-operated devices for the control of electrically operated circuit breakers, small motors, magnetic switches and similar devices. Another important use is for the transfer of current and potential for meters, instruments, and relays. Also, there are many general control applications for which this switch can be used.
