Automatic on/off control for operation at same time each day
Mechanical 24-hour dial with 96 contact trippers at 15-minute intervals
Duty cycle switch for multiple daily on/off operations
480 VAC input voltage, 120 VAC transformed voltage, 20 amp SPDT output contacts
Metal enclosure with locking hasp for indoor use
This NSi Industries 8001-U mechanical time switch accepts 480 VAC input that can be transformed to 120 VAC, and its SPDT output contacts can activate a 20 amp load or 3/4 hp motor. This multipurpose timer has 96 contact trippers with 15-minute intervals for on/off duty cycle operation, and is suitable for use where on/off operation is required at the same time each day. The single-pole double-throw (SPDT) contacts are housed within a metal enclosure that meets NEMA-1 standards for dust resistance and has a lockable hasp. The enclosure is suitable for indoor use and mounts to an external surface. This mechanical timer is Underwriter Laboratories (UL) listed and Canadian Standards Association (CSA) certified 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.
