Atwood 87570
They just pop in, could remove (power off) the motor cover to release from underneath and note wiring-
Ill spray with lube/ helps but I ALWAYS expect switch to stick so am prepared to bump in opposite direction using 2 hand 1 on each switch. Simply dont trust them. The housing just warp. Also lubing the plugs with some dielectric so worse case you can yank it, and to prevent corrosion.
They dont give them away-prices all over the map maybe because of the printed EXT/RET -picture of switch
