Snap-Action Switches Ideal for Power-Industry Applications
WEYMOUTH, MA - Rugged and durable, Series 101 Snap-Action Rotary Switches from Electroswitch are ideal for a variety of power-industry applications. Designed to withstand shock, vibration, and other severe conditions, they feature double-wiping, low-resistance contacts that maintain their set positions inside fully enclosed decks and deliver high-performance DC or AC switching. Available with four-hole or single-hole mounting, they have continuous ratings of 20 amps at 600 volts, but the four-hole model is available with ratings up to 200A@600VAC.
The positive, 90° indexing, snap-action design of Series 101 Switches assures quick make and break action (approximately 10-millisecond transfer time) that is not dependent on the operator. Contacts, which can be either non-shorting (break-before-make) or shorting (make-before-break), are enclosed in molded phenolic insulating disks. To minimize resistance and heating, the stationary contacts extend outside the disks and serve as connecting terminals. Rotation is unlimited and continuous in both directions but can be limited at the factory to two or three customer-specified positions.
Four-hole-mount Series 101 Snap-Action Rotary Switches are available with a choice of seven circuits and can be configured with up to 4 positions, up to 12 poles, and a choice of four handle shapes.
Single-hole-mount Series 101 Snap-Action Rotary Switches are available with a choice of seven circuits and can be configured with up to 4 positions and up to 6 poles.
The insulating materials in Series 101 Switches are rated NEMA Class A (to 105° C). Insulation resistance is 100 Megohms minimum. Approvals for Series 101 Switches include UL File No. E18174 and CSA File No. LR20743. Prices start at $50.00 with delivery beginning @ Stock - 4 weeks ARO.
