W3TS Test Switch

W3TS test switches feature integrated barriers, high quality materials, and our patented safety knob - perfect for modern substations across the grid. Choose from 15 switch elements and a variety of handle colors to create a custom configuration using our web-based design tool. The modular design allows W3TS to be used where only a few (or very many) points may be needed. And W3TS test switches are always made in the USA and backed by the NovaTech 10-year “no hassle” guarantee.
