Description

The Nieco 4099 Toggle Switch 4 Screws ON/OFF DPST is an electrical control component used in commercial foodservice equipment. It provides manual power switching for connected circuits, allowing users to turn equipment on or off through a double-pole single-throw mechanism rated for 20 amps at 250 volts. The switch is mounted using a 1/2-inch panel opening and secured with a four-screw configuration. It is commonly installed in broilers and similar foodservice appliances as part of the control interface, enabling safe interruption or restoration of electrical power during operation, servicing, or routine maintenance within the equipment control system.

More Information:

This toggle switch is used in commercial kitchen equipment to manually control electrical circuits by switching power on and off. It features a DPST (double-pole, single-throw) design, allowing it to control two electrical lines simultaneously. Rated for 20 amps at 250 volts, it is suitable for use in commercial equipment such as ovens, broilers, toasters, and warming units. The switch mounts through a 1/2-inch opening and includes four screw terminals for secure electrical connections within control panels. This type of switch is commonly found in older equipment from manufacturers such as Alto-Shaam, Nieco, Prince Castle, and Vulcan that use toggle-style controls. If the switch becomes loose, unresponsive, or develops poor electrical contact, replacing it can help restore reliable power control and support normal equipment operation.
