ABSTRACT:
An improved toggle switch seal for sealing the opening in a panel through which the toggle switch projects. As contrasted with prior art devices, the portion of the seal surrounding the toggle is relatively thick-walled to prevent ballooning, and is provided with plural annular thin-walled sections to facilitate easy lateral flexing of the seal with movement of the switch toggle, with minimum back-torque tending to return the switch to its initial position. As distinguished with stretching of the thin-walled sections, common in prior art devices, with lateral movement, the seal tends to execute a folding motion in the thin-walled sections tending to reduce the generated resilient forces tending to restore the seal to unstressed condition.
