I cannot figure out how to make ENT:Touch only detect when touching a specific entity instead of detecting anything and everything touching it. It probably has something to do with the argument but nothing I’ve tried has worked

current code (useless)

function ENT:Touch(entity)      
    EmitSound( Sound ("buttons/lightswitch2.wav" ), self:GetPos(), 1, CHAN_AUTO, 1, 75, 0, 100)
    self:Remove()
    end

I’ve tried making the argument the entity name, Using getclass in an if statement (to see if I can do if getclass comes back as the entity run the code) but neither of these or any variations of them have worked.
