This NSi Industries TU40 mechanical time switch accepts 120/208-240/277 VAC input and its DPST output contacts can activate a 40 amp load or 2 hp motor. The switch automatically detects the input voltage and does not require manual setting. LEDs show when the switch is powered and under load. This multipurpose timer has 96 contact trippers with 15-minute intervals for on/off operation, and is suitable for individualized daily operation. The double-pole double-throw (DPDT) contacts are housed within a Noryl plastic alloy enclosure that meets NEMA-3R standards for water resistance and has a lockable hasp. The enclosure is suitable for both indoor and outdoor use and mounts to an external surface. This mechanical timer is Underwriter Laboratories (UL) listed for quality assurance and is suitable for controlling lighting, heaters, and equipment motors.

Automatic switches are used to turn on or off electrical devices and are activated by time, light, and motion. Time activated switches (also known as timers) operate at preset time intervals during a daily or weekly period and can be either mechanical or electronic. Mechanical timers feature a dial with multiple pins to set the on/off time intervals. Electronic timers feature an LCD display and pushbuttons to set the time intervals. Light activated switches (also known as optical or photo) operate when ambient light levels reach preset values, generally measured in foot candles. Motion-activated switches (also known as motion sensors) operate when an electronic field of a preset range is interrupted. These switches can include energy saving logic that uses combinations of time, light, and motion to operate and can include one or more device outlets or circuit contacts. Automatic switches are used to control indoor lights, outdoor lights, appliances, and small equipment motors.
