It's not what project you have in mind that may use a rocket launch switch... The question is what project will you come up with once you have one in hand? Everyone has a proverbial missile to launch. The hot red safety cover protects a toggle switch from accidentally being turned on. When flipped up, the user has full access to a switch underneath. Upon closing the cover, the cover will force the switch arm back into the lower position - a safety mechanism so you can quickly hit the cover down and deactivate the switch. Note: This is the cover for the switch only. A compatible toggle switch is listed below. https://elecena.pl/product/865529/missile-switch-cover-red 2009-07-11 https://elecena.pl/product/865529/missile-switch-cover-red 2016-11-25 https://elecena.pl/product/865529/missile-switch-cover-red 2016-11-28 https://elecena.pl/product/865529/missile-switch-cover-red 2016-11-29 https://elecena.pl/product/865529/missile-switch-cover-red 2016-12-09 https://elecena.pl/product/865529/missile-switch-cover-red 2016-12-13 https://elecena.pl/product/865529/missile-switch-cover-red 2017-11-24 https://elecena.pl/product/865529/missile-switch-cover-red 2017-11-28 https://elecena.pl/product/865529/missile-switch-cover-red 2018-05-05 https://elecena.pl/product/865529/missile-switch-cover-red 2018-11-21 https://elecena.pl/product/865529/missile-switch-cover-red 2018-11-27 https://elecena.pl/product/865529/missile-switch-cover-red 2022-02-21 https://elecena.pl/product/865529/missile-switch-cover-red 2025-04-11 https://elecena.pl/product/865529/missile-switch-cover-red 2025-04-14
