The switch housing is molded from marine grade Polyester, a non-conductive material that eliminates the potential for shorts in wet, corrosive marine environments. An inner seal between the cylinder lock and the contact plate provides maximum corrosion protection and helps eliminate oxidation over time, which keeps the switch working reliably even after repeated exposure to spray and humidity.\u003c\/p\u003e\u003cp\u003eThe switch is finished in white and mounts through a 7\/8 inch panel hole, fitting panels up to 1 1\/8 inch maximum thickness. Hardware includes an anodized steel back up nut and a hex plastic face nut with a snap-on rubber cap to protect the terminals from moisture. Electrical connections are made via 6 screw tab terminals, and the switch is rated for 15 Amp at 12 Volts DC on ignition, 30 Amp at 12 Volts DC on the solenoid circuit, and 7 Amp at 12 Volts DC on choke. It is a universal fit switch, making it a straightforward replacement wherever a 3-position magneto ignition switch with push-to-choke operation is needed.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
