MERZ has long been the industry standard in UL certified switches. MERZ cam switches are second to none for quality and reliability. Springer Controls-MERZ switches are available in models from 16 amp to 125 amp. These UL certified switches are suitable for residential and industrial applications. This item is a 4-screw, front-panel mounting-cam switch. Both the switch and the handle are attached to the panel or wall by these four screws (included.) Cam switches, according to their contact arrangement, are fitted with switching chambers with 1, 2, or 3 (series 111 only) double interrupted ...

This disconnect switch is designed for use with an enclosure. The handle mounts to an enclosure door (4-hole.) The switch mounts to a din-rail (rear.) This switch requires a shaft-extender (sold separately.) There are a variety of adjustable shaft-extenders available to ensure a perfect fit.

22mm Non Metallic, Non Illuminated, 3 Pos. Maintained, Square Knob Type Selector Switch - Black 22 mm Non-Metallic Pushbuttons are heavy duty industrial control devices available with a wide range of Illuminated and Non-Illuminated Operators. The buttons are fully gasketed for Type 4X (IP65) protection. This is to prevent the entrance of water, oil, and dirt past the operator into the enclosure. The modular construction makes "on the job" assembly both fast and simple. The contact blocks are "stackable" (up to a maximum of 4 contact blocks) allowing many combinations of control layouts.

One-way DC controls are designed to operate permanent magnet or wound field motors. If the motor's rotation needs to be changed, the armature leads need to be reversed. Some NEMA 1 and NEMA 4X controls offer optional switched for reversal. Stopping of a motor with a one-way control should be done by dynamic braking, some controls offer the Forward-Brake-Reverse switch for this purpose too. Features Full wave SCR control with free wheeling diode (NEMA type K) Field power supply allows use with shunt wound DC motors as well as permanent magnet motors Adjustable accel, decel, current limit, ...
