Intermatic SW15MWK 15-Minute Spring Wound Timer – Energy-Saving Control for Lights & Appliances

Overview

The Intermatic SW15MWK is a compact spring wound timer that operates without drawing power from the line. It is designed to replace a standard wall switch in single or multi-gang installations and automatically limits the ON time of energy consuming loads such as lights, fans, motors and heaters for a controlled use.

Key benefits

• Controls LED and CFL lights for compatibility with modern energy saving options
• 15 minute off control helps keep light and equipment use within a predictable window
• No electricity required to operate the timer itself
• Designed for easy replacement, it fits standard wall plates in single or multi-gang boxes
• Versatile usage for a range of devices, providing simple automation for everyday tasks

Load compatibility and ratings

• Resistive heater 20A at 125 VAC; 10A at 250/277 VAC
• Tungsten 7A at 125 VAC
• Motor 1 HP at 125 VAC; 2 HP at 250 VAC

Dial and installation

The unit ships with a molded white dial plate designed to fit toggle or decorator style switch plates, in single or multi-gang configurations. An exclusive upfront terminal connection with teeter type terminals and a press on knob enable quick installation. A CSA certification adds assurance of safety and reliability.

Practical use scenarios

Imagine turning a bathroom light or hallway lamp on for a short period while you dress or prepare, then have it shut off automatically. In a workshop, a small fan or motor can operate only for a set interval, reducing energy use and heat buildup. The no power timer itself reduces standby consumption while offering real control when you need it.

Easy installation and safety notes

Install in place of a standard switch without rewiring. The front terminals simplify wiring and testing, and the compact form blends with existing hardware. Always follow local electrical codes and use CSA certified equipment for safety.
