The low-profile design of the 400B Series process sealed SMT rocker switch permits right-angle mounting along the edges of circuit boards. The actuator is designed to project beyond the circuit board far enough to be accessible through an enclosure or instrument case slot, reducing the need for expensive remote wiring. The switch has an electrical life of 6,000 cycles and a mechanical life of 50,000 cycles. To cover the broadest range of functional applications, five different options are available for the three rocker positions: On-None-On; On-None-Mom; On-Off-On; Mom-Off-Mom; and On-Off-Mom. Switches in this series are available with either silver- or gold-plated contacts.
