Snap Action Rotary Switch - 30 Amp

Our snap-action rotary switch is a heavy-duty industrial rotary switch designed for switching resistive loads at higher currents and voltages than typical control-circuit switches. Rated for 30 amperes maximum at 600 VAC, this switch handles power-circuit switching duties directly — bypassing the need for external contactors or auxiliary relays in applications where a manual rotary operator can switch the primary load. Precision snap-action contacts break and remake independently of operator rotation speed, providing consistent contact-transfer time and extended contact life under repeated switching.

Closed-construction stack design protects internal components from dust, debris, and casual contact, and multi-pole configurations allow complex switching arrangements — such as multi-phase source selection, multi-position transfer schemes, or motor mode controllers — in a single panel-mounted unit. Contact materials are chosen for reliable make-and-break at rated current with minimal degradation over long service life, and the modular deck construction supports both shorting and non-shorting contact configurations to match sequencing requirements. Terminal options include screw and quick-connect styles, and standard panel-mount hardware simplifies installation in industrial control panels, machine tools, and utility switchboards.

Typical applications include manual source-transfer switches, motor mode selectors on machine tools, heating-element multi-tap controllers, industrial process-control panels, and any multi-position rotary control requiring higher current and voltage capacity than standard control-circuit switches provide. This switch is available in a wide range of pole and position combinations to match specific application requirements.
