OTTO Introduces the New K1S - The Industry's Smallest ON-ON-ON Triple Throw Rocker Switch
The K1S is a short-behind-panel, sealed, logic level only rocker switch offering 1M cycle life in a snap-in package.

Available in both single and double pole configurations with maintained action. This ON-ON-ON rocker is perfect for use as a Forward-Neutral-Reverse (FNR) switch. The double pole version offers redundancy for each switch state providing increased safety. Termination options include a Molex connector or wire leads.

The K1S contact system is sealed to IP68S and uses a flow-thru design. With an optional boot, the switch is panel sealed to IP68S. The rugged K1S is shorter behind panel than OTTO’s K1 rocker series, making it an ideal choice for use in grips and panels.

The K1S also consists of two rocker button style/size options for best user comfort. Only one panel opening size is required, regardless of button size, and it features a snap-in design. Choose from a set of 73 standard legend choices which are offered with both normal and large-size rocker top styles, or add a custom logo, lettering or legend.
