A contract address is not a repository of tokens like a typical wallet; it is essentially a computer program, a set of code, that performs some function on the blockchain. If you send any number of tokens to a contract address, there is no guarantee anyone can retrieve your tokens. In the case of Switch unfortunately, your tokens cannot be retrieved.
Disclaimer: SWITCH is a digital reward distributed through the Switch node network according to predetermined smart contracts. SWITCH is designed to have utility on the Switch platform for the purchase of Switch products and services, although other cryptocurrencies may be used as well. SWITCH is not available for purchase from Switch. SWITCH is not an investment product and may never have any value. Switch node owners should not expect to recognize any value from SWITCH other than its utility with Switch. Although Switch plans to undertake efforts to become a successful business, it is highly likely that SWITCH’s value will not correlate with the success or failure of Switch.
