The Canon Remote Switch 60-T3 is an electronic cable release for use with the T70, T90, EOS 650, 620, 750, 850, 630, 1, RT, A2, A2e, 1N & 1N-RS cameras.
Why Canon advertised it on their site as compatible with the Canon 40D (which I used to use), the good Lord only knows. However, it is far too long since I bought it to get a refund now.
Anyone with one of the cameras listed in the top paragraph, interested in a remote switch, drop me a site mail.
